It has been revealed that nine-year-old Lin Miaoke, who performed “Ode to the Motherland” during the ceremony, was only a visual effect. A recording of another girl’s voice played throughout the stadium and on the television and radio broadcasts. It is also now known that that some of the fireworks shown on television were computer-generated imagery.

The New York Times reports Lin’s voice was not perfect, and a member of the Chinese Politburo demanded that a more suitable voice was used. Organizers found that voice in seven-year-old Yang Peiyi. Another girl was used in rehearsals, but she was deemed to be too old.

“The reason was for the national interest,” Chen Qigang, the opening ceremonies general music designer, said Sunday during a radio interview. “The child on camera should be flawless in image, internal feeling and expression.”

“She’s very cute and sings quite well, too,” he said according to a transcript of the news conference. “I was moved every time we did a rehearsal on this, from the bottom of my heart.”

The initial performer was a ten-year-old girl who was not named in the report and “whose voice was really good,” but Zhang decided that she was too old. About ten girls were auditioned for the role at Central People’s Radio Station in Beijing.

“After the recording, we thought that Lin Miaoke’s voice was not very suitable,” Chen Qigang said during his radio interview with Beijing Music Radio. “Finally, we made the decision that the voice we would use was Yang Peiyi’s.”
